Two previously healthy patients, a 66-year-old man with blunt trauma to the right eye, and a 28-year-old man with head trauma from a motorcycle accident, were observed to have parafoveal retinal pigment epithelial tears after injury. In both patients, fluorescein angiography demonstrated mottled window defects in the areas of the tears, and blocked fluorescence in the areas of the rolled-up pigment epithelium. Neither eye had evidence of pigment epithelial detachments. We hypothesize that this unusual phenomenon is caused by an acute tractional force oriented tangentially to the macular plane, the result of a rapid spherically expansile deformation of the globe during trauma.
两名既往健康的患者,一名66岁男性右眼钝挫伤,另一名28岁男性因摩托车事故导致头部外伤,受伤后均被观察到黄斑旁视网膜色素上皮撕裂。两名患者的荧光素血管造影均显示撕裂区域有斑驳的窗样缺损,以及卷起的色素上皮区域的荧光遮挡。两只眼睛均无色素上皮脱离的证据。我们推测这种不寻常的现象是由与黄斑平面相切的急性牵引力引起的,这是外伤期间眼球快速球形扩张变形的结果。
